Before You Begin

Restrictions

This task is performed in the Cisco IOS command-line interface (CLI) of the gatekeeper.

Procedure

On the Cisco router, enter privileged EXEC mode or any other security level set by a system administrator. Enter your password if prompted.

Router# enable

Enter global configuration mode.

Router# configure terminal

Enter interface configuration mode.

Router(config)# interface type number

Configure the IP address and subnet mask used by this gateway.

Router(config-if)# ip address [ip-address][subnet-mask]

(Optional) If you configured a Fast Ethernet interface, configure duplex operation as auto, which specifies the autonegotiation capability. The gateway automatically operates at half or full duplex depending on environmental factors, such as the type of media and transmission speeds for the peer routers, hubs, and switches used in the network configuration.

Router(config-if)# duplexauto

(Optional) If you configured a Fast Ethernet interface, configure the speed for this gateway.

Configure the H.323 name of the gateway identifying this gateway to its associated gatekeeper.

Router(config-if)# h323-gateway voip h323-id hostname

Define the technology prefix that the gateway will register with the gatekeeper.

Router(config-if)# h323-gateway voip tech-prefix prefix

prefix-Defines the numbers used as the technology prefixes. Each technology prefix can contain up to 11 characters. Although not strictly necessary, a pound (#) symbol is frequently used as the last digit in a technology prefix. Valid characters are 0 though 9, the pound (#) symbol, and the asterisk (*).

Exit the current mode.

Router(config-if)# exit

Enter gatekeeper configuration mode.

Router(config)# gatekeeper

Configure the zone name and the name of the domain served by this gatekeeper.

Optionally, you may specify the IP address of one of the interfaces on the gatekeeper. When the gatekeeper responds to gatekeeper discovery messages, it signals the endpoint or gateway to use this address in future communications.

Set the gatekeeper port for Registration, Admission, and Status (RAS) signaling to 1719. This is the default.

Configure the technology prefix, also called the gateway-type prefix.

Router(config-gk)# gw-type-prefixtype-prefix

End your configuration session by exiting to privileged EXEC mode.

Router(config-gk)# end

Example

In the following Cisco IOS configuration example, the gatekeeper router hostname gk-1.example.com is also used as the zone name. Matching these names is not necessary but simplifies administration.

This task is performed in the Cisco Unified Communications Manager Administration pages. Because the pages and menus vary by Cisco Unified Communications Manager release, you may need to see the Cisco Unified Communications Manager online help for more accurate step-by-step instructions than those provided in this procedure. The following procedure refers to Cisco Unified CallManager Release 4.1.

f. Configure the fields described in [[Cisco Unified MeetingPlace Express, Release 2.x -- How to Integrate With a Call-Control Device Through a
Gatekeeper#Table: Fields for Adding A New Trunk to Cisco Unified CallManager|Table: Fields for Adding A New Trunk to Cisco Unified CallManager]].

Table: Fields for Adding A New Trunk to Cisco Unified CallManager

Trunk Configuration Field

Action

<td colspan="2" rowspan="1">
Device Information</td>

Device Name

Enter a unique identifier for this trunk, such as the name or IP address of the Cisco Unified MeetingPlace Express server.

g. For all other required fields on the Trunk Configuration page, configure the fields appropriately for the current Cisco Unified CallManager deployment. For information about each field, see the Cisco Unified CallManager online help or see the administration guide for your specific Cisco Unified CallManager release.

h. Click Insert.

i. Click Reset Trunk to have the changes take effect.

5. Add a new route pattern to Cisco Unified MeetingPlace Express through the gatekeeper by completing the following actions:

7. (Optional) If you have multiple Cisco Unified MeetingPlace Express access numbers, repeat Step 5 for each access number. This includes phone numbers entered on the Usage Configuration page as well as direct meeting dial-in numbers.

This topic describes how to configure Cisco Unified Communications Manager Express and other Cisco IOS software voice-enabled routers to integrate with Cisco Unified MeetingPlace Express through a gatekeeper.

Restrictions

This task is performed in the Cisco IOS command-line interface (CLI) of the router. For more information about the Cisco IOS commands used in this procedure, see the Cisco IOS Commands Master List for your Cisco IOS software major release.

Procedure

On the Cisco router, enter privileged EXEC mode or any other security level set by a system administrator. Enter your password if prompted.

Router# enable

Enter global configuration mode.

Router# configure terminal

Enter interface configuration mode.

Router(config)# interface type number

Configure the IP address and subnet mask used by this gateway.

Router(config-if)# ip address [ip-address][subnet-mask]

(Optional) If you configured a Fast Ethernet interface, configure duplex operation as auto, which specifies the autonegotiation capability. The gateway automatically operates at half or full duplex depending on environmental factors, such as the type of media and transmission speeds for the peer routers, hubs, and switches used in the network configuration.

Router(config-if)# duplexauto

(Optional) If you configured a Fast Ethernet interface, configure the speed for this gateway.

Configure the H.323 name of the gateway identifying this gateway to its associated gatekeeper.

Router(config-if)# h323-gateway voip h323-id hostname

Define the technology prefix that the gateway will register with the gatekeeper.

Router(config-if)# h323-gateway voip tech-prefix prefix

prefix-Defines the numbers used as the technology prefixes. Each technology prefix can contain up to 11 characters. Although not strictly necessary, a pound (#) symbol is frequently used as the last digit in a technology prefix. Valid characters are 0 though 9, the pound (#) symbol, and the asterisk (*).

Set the source IP address to be used for this gateway. This command binds all H.323 messages from the gateway to this IP address.

This topic describes how to enable your call-control device to route calls to Cisco Unified MeetingPlace Express by configuring a dial peer. Configuring dial peers is the key to implementing dial plans and providing voice services over an IP packet network. Dial peers are used to identify call source and destination endpoints and to define the characteristics applied to each call leg in the call connection.

Restrictions

This task is performed in the Cisco IOS command-line interface (CLI) of the router. For more information about the Cisco IOS commands used in this procedure, see the Cisco IOS Commands Master List for your Cisco IOS software major release.

Procedure

On the Cisco router, enter privileged EXEC mode or any other security level set by a system administrator. Enter your password if prompted.

Example

The following example displays dial peers that were configured to direct calls to a primary Cisco Unified MeetingPlace Express number and an alternate Cisco Unified MeetingPlace Express number using RAS.

When you modify the parameters on the H.323 Configuration page, Cisco Unified MeetingPlace Express reinitializes H.323 signaling with the call-control device. During the reinitialization process, which can take up to 2 minutes, calls and voice meetings may be affected.

Procedure

Log in to Cisco Unified MeetingPlace Express and click Administration.

8. Test this integration by placing a call from any phone to the phone number that is used to access the Cisco Unified MeetingPlace Express system. You should hear the "Welcome to Cisco Unified MeetingPlace Express" greeting.
